Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
As shown in fig. 1 to 4, the embodiment provides a rotary drilling rod with a high-strength wear-resistant disc, which is characterized in that: the drill pipe 1 is sleeved on the square head 8, the mounting hole 4 is formed in the square head 3, the square head 8 penetrates through the mounting hole 4 to be connected with the water flowing disc 3, more than two water flowing grooves 5 are formed in the top end of the water flowing disc 3, the wear-resistant disc 2 is abutted between the drill pipe 1 and the water flowing disc 3, and the hardness of the wear-resistant disc 2 is higher than that of the drill pipe 1 and the water flowing disc 3. In this embodiment, the wear-resistant disc 2 is made of a steel sheet with high hardness, the wear-resistant disc 2 is arranged between the drill rod 1 and the flow disc 3, the drill rod 1 rotates and drives the wear-resistant disc 2 to rotate under the action of friction force, and because the hardness of the wear-resistant disc 2 selected for use in this embodiment is higher than that of the drill rod 1 and the flow disc 3, the end face with lower hardness is worn when the drill rod 1 or the flow disc 3 is in friction with the wear-resistant disc 2, so that the surface of the drill rod 1 or the flow disc 3 is worn uniformly, and the service life of the drill rod 1 is prolonged.
In order to enable muddy water in the drill rod 1 to be smoothly discharged out of the drill rod 1, more than two water flowing holes 6 are formed in the end face of the wear-resisting disc 2, and the water flowing holes 6 are in a long strip shape. When mud water flows downwards from the interior of the drill rod 1, the mud water is guided through the water flowing hole 6 and flows into the water flowing groove 5 on the water flowing disc 3, and then flows out of the drill rod 1 through the water flowing groove 5.
In order to prevent the wear-resistant disc 2 from rotating, the water flowing holes 6 and the water flowing grooves 5 are staggered to block the water flowing holes 6, and further, the water flowing holes 6 and the diameter direction of the water flowing disc 3 are arranged at a fixed angle. Through setting up a plurality of discharge orifices 6 to with discharge orifices 6 along flowing water dish 3, make no matter how wear-resisting dish 2 rotates, discharge orifices 6 homoenergetic and tye 5 intercommunication, effectively prevented the condition that muddy water in the drilling rod 1 can't discharge and lead to square head 8 to block up.
In order to fix the water tray 3 on the square head 8, a bulge 7 is further arranged on the inner wall of the mounting hole 4. Because the side of square head 8 is provided with the draw-in groove, with arch 7 and draw-in groove cooperation for flowing water dish 3 can not rotate with square head 3 relatively, prevents that flowing water dish 3 from rotating and wear-resisting dish 2 friction, improves flowing water dish 3's life.
In order to facilitate replacement of the wear-resistant disc 2, further, the wear-resistant disc 2 is sleeved on the square head 8. When the wear-resisting disc 2 is seriously worn, the square head 8 is taken out from the drill rod 1, and the square head 8 is sleeved on the drill rod 1, so that the wear-resisting disc 2 can be directly taken down and replaced from the upper part of the square head 8, the effect of quickly replacing damaged parts is achieved, and the construction speed and efficiency are improved.
In order to prevent the drill bit from falling into the pile hole due to the breakage of the square head 8 in the drilling process, further, as shown in fig. 5, the square head 8 includes a connector 801, a spring seat 802, a fixing plate 803, a connecting rod 804, a circular ring 805 and a fixing pin 806, the spring seat 802 is fixedly disposed on a side surface of the connector 801, the fixing plate 803 is disposed at a top end of the connector 801, the fixing plate 803 is detachably connected to the connector 801, a through hole 807 is formed in the connector 801, a pin hole 9 is formed in a side surface of the connector 801, the pin hole 9 is communicated with the through hole 807, the fixing pin 806 is disposed in the pin hole 9, the circular ring 805 is sleeved on the fixing pin 806, the connecting rod 804 is further disposed in the through hole 807, one end of the connecting rod 804 is rotatably connected to the fixing plate 803, and the other end of the connecting rod 804 is fixedly connected to the circular ring 805. During the construction, be fixed in the connector 801 with the drill bit through fixed pin 806 on, drilling rod 1 rotates and drives square head 8 and rotate, square head 8 drives the drill bit and carries out the drilling operation under the effect of fixed pin 806, when the too big square head 8 fracture that leads to of moment of torsion of drilling rod 1, because connecting rod 804 is connected with fixed plate 803 is rotated, consequently drilling rod 1 continues to rotate and can not twist off connecting rod 804, thereby at the in-process of mentioning drilling rod 1, fixed plate 803 can together propose the stake hole with drill bit and cracked square head 8 through connecting rod 804, avoid the drill bit to fall into in the stake hole, influence the construction.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the invention. The present invention is not to be limited by the specific embodiments disclosed herein, and other embodiments that fall within the scope of the claims of the present application are intended to be within the scope of the present invention.
